I’ve noticed in several woodworking videos that people sometimes seem to struggle adjusting their parallel clamps, so maybe this will help.
I just bought my first batch of the Jet parallel clamps last week during the Black Friday sale, and they were delivered today. After opening them up and playing with them, I noticed that the movable jaw was easy to move on some, but very difficult to move on others. For example, on some I could close the jaw without having to pull the quick adjustment trigger, but on others the jaw wouldn’t move unless I pulled the trigger. On at least one of the clamps, the jaw was really stubborn even when I pulled the trigger.
I’m still not quite sure if you’re supposed to have to pull the trigger to close them or not, but after some experimentation with one of the clamps it seems that if you loosen/unscrew the handle all the way (as you do when loosening the clamp), the jaw slides closed more freely; and if you screw the handle in as far as it goes (all of mine stop with about 1/4”-1/2” of the threads still exposed on the handle side of the jaw), the jaw doesn’t move at all, even when you pull the trigger. Has anyone else noticed this, and is this how other brands of parallel clamps also work?
